摘要：

We investigate the polarization characteristics of GaInP vertical-cavity surface-emitting lasers (VCSEL's) as a function of substrate misorientation and quantum-well strain, All the structures investigated show dominant polarization along the [110] direction, The polarization selectivity is found to be essentially independent of QW strain but increases significantly as the substrate misorientation is reduced from 10 degrees to 3 degrees. These results provide clear experimental evidence that the major contribution to the polarization characteristics of GaInP VCSEL's is a consequence of ordering-induced gain anisotropy.
